back gluing machine

An edition binding machine used to glue up the
spines of books and automatically convey them
along a drying section which quickly sets and
hardens the glue. The maximum size book that can
usually be processed in such a machine is 12 by 9
inches, and the minimum 3 by 2 inches, with a
thickness up to 2 1/2 inches. A fully automatic
back gluing machine can process up to 2,400 books
an hour. See also: TRIPLE LINER AND
